# Scientists Thought Ancient Water Carved Martian Gullies. New Analysis Says Otherwise

> **Open Intelligence Dossier** · First detected: 2026-09-15 08:23 UTC · Category: Science

## Executive Summary
Recent scientific analysis reveals that Martian gullies were carved without liquid water.

## Intelligence Brief
Recent scientific analysis challenges long-held assumptions regarding the geological features of Mars, according to coverage from multiple outlets including Phys.org, Gizmodo, The Daily Galaxy, Root-Nation.com, and srpske.rs. Coverage details how scientists have discovered a new explanation for the gorges and Earth-like gullies found on the Martian surface. For years, conventional scientific understanding held that ancient water carved these distinct formations. However, new findings indicate that active gullies on Mars are being shaped without a single drop of liquid water, shifting the focus away from traditional aquatic theories.


Outlets such as Gizmodo and Phys.org emphasize that a fresh analysis of these planetary features points toward alternative geological mechanisms. The Daily Galaxy and Root-Nation.com report that scientists have identified dry ice as a key factor in this process, noting that the gullies are carved by dry ice rather than flowing water. This new perspective reevaluates previous models of Martian geology, which heavily relied on the presence of ancient water to explain surface morphology. The revelation that Earth-like gullies can form through dry ice processes provides critical context for understanding planetary mechanics under different atmospheric conditions.


While earlier studies focused on liquid flows, the current scientific consensus reflected in the coverage directs attention toward frozen carbon dioxide and its physical interaction with the Martian terrain. Readers and observers must monitor upcoming scientific publications and research updates for further details on the specific mechanisms of dry ice erosion on Mars. The coverage does not yet specify the full timeline for subsequent research phases or whether related planetary formations will be re-examined under this dry ice framework. Further scientific announcements will clarify how these findings alter broader models of Martian climate history and surface evolution.
